IMPROVEMNT IN AIR-TIGHT`CANS.

-Ph- The Schedule ret-erred to in theseLettexl' Patent and making put ofthe hama.

To all whom it ma/y concer/1i:

Be it known that I, W. IGORDON, of Philadelphia,

in the county of Philadelphia, and State of Pennsyl- Vania, haveinvented a new and useful Improvement in Air-Tight Cans; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to make and use thesame, reference being had to the accompanying drawings, forming part ofthis specification.

, This invention relates to a new and useful improvement in cans forpreserving fruit and 'other articles, and for containing lye,^paint, andall substances f a similar nature; and consists in the manner iu whichthe can is closed, as 'will be hereinafter more fully described;

The accompanying drawing represents a. can constructed or closedaccording to my invention.

A is the can, which is a plain cylinder, with top and bottom soldered onin theusual manner; but the top B has an orice suiciently large to allowof the .filling of the with fruit, or any-article which it .may bedesired to preserve air-tight, (or otherwise,)` for' sale or use.

The top is beaded, and s shaped by swaging, so

that the edge is turned down atan angle inclining in-v ward, as seen inthe drawing at c c.

D represents the cover or disk which fills thefoice. This cover or diskAis swa'ged out or formed v wvitlia ange, e, the upper portionof whichis made to tthe angle c of the top B.

Thediameter of the lower portion corresponds with that ofthe lower edgeof the orice, or'it may be a trifle largerthan the orifice, so that whenit is forced down, the oriice willnot only be closed air-tight, but

there will be sufcient friction to hold the cover tightlyV in place.

Gare is taken to have a perfect edge to'the lip. or bevel c in the top,and also to have the cover correspondingly perfect, so that when it isAforced into the orifice the joint shall be complete.

By this arrangement all machinery for closing the can is dispensed with.

The label (stating the contents of the can) is placed over `the cover D,and the can is readyfor'market, thus greatly lessening the expense andtrouble of putting up fruit, or properly securing paint, lye, and otherarticles of a similar nature.

`Having thus described 'my invention,

I claim as new,` andl desirer to secure by Letters Patent-y v VIncombination Vwith a can,` when the top is formed with an 'inclinedsurface c, the cover D, constructed and applied substantially asdesclibed and for the pur-4 poses vset forth.

` W. J. GORDON.
